Machines can fail when signals get messy from electrical noise. These new isolators keep signals steady and systems running without errors.

Modern industrial and automotive systems rely on fast, accurate communication between multiple components. But in real-world environments, electrical noise is everywhere, whether from motors, switching power supplies, or other devices. This noise can distort signals, cause control errors, or even lead to equipment failure. At the same time, many systems require high-speed communication across multiple channels, for functions like sensors, I/O interfaces, or embedded controllers. Standard isolators often struggle to provide both noise immunity and high-speed performance, leaving engineers to choose between reliability and speed.
Toshiba’s DCL52xx00 Series digital isolators address these challenges. With a high common mode transient immunity (CMTI) of 100 kV/μs, they can withstand severe electrical noise while keeping signals intact. They also support data rates up to 150 Mbps and have very low pulse width distortion, making them suitable for multi-channel, high-speed applications such as UART and I2C interfaces.
The series includes flexible channel configurations to match different system needs. Some models have two forward channels, while others combine one forward and one reverse channel. This gives designers more options to integrate reliable isolation without adding complexity or extra components.
These isolators use the company’s magnetic coupling isolation method, which provides strong, stable separation between input and output. This makes equipment less prone to signal errors, improves overall system stability, and reduces the risk of downtime caused by noisy environments.
The company has started mass production and plans to expand the lineup with additional package and channel options. For engineers building industrial or automotive equipment, these isolators solve a critical problem: keeping high-speed signals accurate and reliable, even in harsh, electrically noisy conditions. The Series makes it easier to design robust systems without compromising on speed or functionality.
